To all whom 'it may concern. i

Be it known that I, ALennrC, SCHULZ, n

citizen .of the United States, and a resident fof Bridgeport., county of Fairlield, State of (lonnecticut, have invented an Improvement :in Dumping and Removable Bodies, of Wlueh the following description, in connection with 1"'5 lexis/' y`invention will be beet understood by the accompanying drawings, is a. specifica 'u tion, like characters on the drawings repre 1.04-

senting like parts. This invention relates to londing and unn *loadingg apparatus, and more especially, thol'lgh not exclusively, to dumping and `re- 'lnovable bodies for trucks, more partici 4motor trucks.

reference to the following specilica tion, when taken in Connection with. the nceompmiying illustratioznof one specific embol'liinent thereof, While its opewill be more particularl y pointed outin theappended claims.

Inthe drawings r,

F`gure 1 is e. side elevntionof a motor trlielt embodyingmy invention;

Fig. 2 is a side relevent-ion4 of a motor truck showing the bodyiln ite dumping position;

Fig is n. plan of a portion of the truck with the body removed; Fig. 4 's e. plan of a portion of the truck with the body removed;

Fig. 6 is a sectional View on line G---G of g. 7 Ais a longitudinal section on line 7--7 'of Fig. 4; 4

v,Fi 8, is a sectional view on line L48 'of l frame.

Referring to the drawings", end to the embodiment of my invention which I have selected for illustrativepurposes, I have there shown a motor truck having a frame, herein comprising a pair of side members .l-l, tied together by cross members 2., 3, 4 and 5. This frame supports a guidejvay to' sustain thev body, said gnideway being herein in the form of a track comprising two rails 6-.6, which may be in the form of channel mem bers having uptnrned flanges forming guides for' the body 'Wheels which will be presently described.

Mounted in :mv suitable manner upon this track is a body l, l*Which muy be and preterably is provided with a plurality ot' pairs of wheels 8-8, 9-9, 10,-10, and ,l1-11, journaled in suitablebenring brackets 12-`l2, 13-13, 14-14 and 15M-15, secured to the body.- These wheels are arranged to travel upon the 'channel mile 6 6, and are guided by the 11p-turned ienges of the latter. A pair of supporting arms lil-16 secured to l the frame constitute in effect continuations 'Wheels and when the body is being rep-laced upon the truck frame, if there is any mlsalinement between the body and 'truck frame,

thev flanges on one side or the other will serve to guide the Wheels and compel them to roll into their proper planes upon the rails 6-6.

' As af ineens for preventing the body wheels from being` lifted olf of the rails 6-6, there may be providedsuitable means on the frame engaging with a part. carried by vthe body, as for example, a ,pair of brackets 22-22, secured to the side members 1-1, and having inwardly projecting lugs or flanges 23-23, beneath' which are located pins 2%24 carried by the brackets 13-13 respectively. Preferably, lthe lugs or flanges 23 are" inclined, downwardly towardthe." 4

b bolts 42.

front of the vehicle, so that when the body is brougl'irA forward inlo itsv norfual position, the downward inrlinaliou of tlu.` flanges will uct lhrough thil plus il lo #anse thil wheels 5 tolle drawn down liluily against their rails.

thus 'irinlv holdin;A llu body in its norlnal position.

The truck may be provided. with any suitable driving nwans, hul herein hasl a motor,

or engine, ifi, which drives the truck through suitable nuwluinilsiu, inrludiug a main rlutrh 2G of eonunon loi-nl. a lshall 27 and transmis-1 sion mechanism inrludiujg, a pinion 2S, se cured to the shal't 2T. and permane ntly mesh hui with and drivinga gear 2f) secured to a counter-sha l'iy Pill. .'\rran,ed in line witlrthe shaft 27, is a main shafi Ill. having thereon a pair of sliding gears lvl und i, iluI l'ornwr being adapted to he iueslwd uilh a gear Ill,

secured to the counter-.shalt 30, and tlu` adapted 1o lw nier-hud wuh a serondgear 35. also secure-(llo the rounlrr sha'lt. The fearing thus briefly elesrrihod forms simply a parl of a Connnou l'orni ol other Ibeingr lranslnission rearing which is ntilizvd in a well known luaunur lo .provide a series ol (liflerent ratios between the ,engine and dru- 111;,Y wheels. 'The slidingr ,gears 32 and 25? are shown 1n Fig. 'lin what is ron'nnonliT -known neutral position, and when these gears are' in this position, and the main clutch 2G is engaged, the er nner-shall. 30 will be driven by the gears and '152. .lt will be unnecessary to' further describal the drivinp,r mechanism of the truck, sinee .it will he similar :in its` general features to eornu'mn y forms of motor vehicles.

I will now describe the mechanism by which the power of the truck drivingI engine 40 or motor is utilized to dump the load or .remove the body from the truck frame and replace the same. thereon at will.. .lournaled 'in suitable bearings 36 and 37 on the Cross meinbers 2 and 5,.respecti\"ely, is a .fix-(L screw 38 having thereon a feed-nut 39 (Figs.

3, 1l and 12).- The feed-nut may be provided4 with vertical trunnions 4(l--4-0,-inr nml' ed in a yoke formed in two parts dll-Jfl secured together about the trunnions 4()- by As a means for preventingA thel nut from rotating about its axis. this yoke is provided with laterally projefr-tin, r ftrunnions L3-43, on which are journaled rollers 14T-44, arranged to travel Iin a. pair of `55".,9guiiles 45-'-45, herein formed by -pairs of angle irons t6-4.6 seeured to angle irons 47--47, the latter being mounted upou the cross members 2, 3 and 4 of the trarne. By this means', the nut is held against rotation,

(5o-arid the rotation of the screw is utilized to move the nut longitudinally for thil purpose which will presently appear.

v The nut 39 may be connected to the body 7 by any suitable means, but. herein there is as nrovided a link 48f0rked at ils forward end la ,liseonnevted at will, when itis desired t0 ri-iuove the body from the fraaie of the truuk` 'l`lurear end ol the link 'i8 is connor-ted to the body preferablyY by a universal munvetion, herein.comprising a stud 50 'seeurrd to the bod)Y thereon a block 5l provided with lrunnions in thi,` Jr'oriu of studs pivoted in a 'l'ork Si. at the rear end of the link By Iludosrribed connections, the body link 48 is universally ronnecled lo the lnidy as well as to lhe feed-nul, so that in remounling lhe hodv ou the truck frame, the body and fraaie may he out of line, and the link i5 run still lul 'plugged u ith (he trunnions 43 of the lordnul lill.

li will now be evident that ln' rotating Ihrl l'rczd-srrvw in the propt-r diri-ation. it will :uit through (he lfeed-nul and bolli' link to niovo the l'ifulv rearwardly ol forwardly alonh'llu l'rauu. ll will also hr midi-nl that when ihr lood-.arrow is not rotated; the described runnin-lions will serve as a means l'or loi-kiner the body, against .longitudinal movement.

The leeil-srrevv may be driven hv the motor b v :inv suitable mechanism, but herein it is driren bv mechanism rounccting the leerlas-(freir with the eountershalt 30. Preferably this mechanism affords means of" eonneeiing, lthe leeds 1'e\\' willi` anrldiseonxii-cling the same from the ronxnershaft and driving` the feed-screw in either direction at will. llerein the feed-seriw is provided at its forward end with a sprocket 'wheel-54 connected by a, elia-in to a sprocket wheel 56,' the latter being,r secured to a shaft 57 journaled in suitable bearings 58 'and in a gear rase or housing (il).

Mounted loosely upon this shaft is a spnrgea'r (il and a sprocket Wheel 69,. The spur 1rear ('fl meshes with a spur gear 63 secured lo a shaft G4, journaled in suitable bearings (l5 and 66, in the ,gear Case (i0. f sprocket wheel (i7 also secured to this shaftronneeted to the sprocket Wheel G2 by a chain G8. The shaft (i4 may be connected to; the transniissi'on eountershaft 30 by any suitable means, but herein the transmission mechanism is provided within gear Case or housing: C9, having an extension forming a easing for a clutch 7l. which may be utilined at will to connect thetransmission counter-shafl'- 30 with, and disconnect the same from the shaft 64. The eluteh 71 and haring pivotecl r1n which is located a. yokenions 100 pivoted in a fdrked clutch shift? may be of any suitable type, but herein the members 72V and 73 are provided with suitable inlcr-engagiiip; iawss, or lugs 7T and 78 nl' common form.

'The clutch member 73 may be shifted into and .out ol engagement with the clutch nicmbcr 72 by uny' suitable means', but herein is provided with a circlnnlerential groove (9, which receives a yoke 80, having tr'unnions 81 pivotcd in a. forked clutch shifting arm 82 of com 'rnon form', the latter being secured to u. roelcshaft 83 mounted in suitable bearings in the casing 70. `Secured to the shaft 33 is a 4lever 84 connected by a link 85 to one arm 86 of a bell-crank lever 87, the other arm 88 of which is connected by a linli '89 to a lever 90, secured to a'shnft 91.

In. order that the feed-screw may be driven. in either direction at will, the gea (il or the srocket wheel 62 may be secured to the siiaft 57 by any snitablei'orm of clutch 92, herein comprising; a shiftable member 93, siidably but non-rotatably mounted unen the o' suitnhle teeth or iews 94 and95, afl-ap o hc ein gagged respectively with. corresironding sets of teeth or jaws 96 and 97, omistitutmg clutch members on the gears 62 und, 31 reH spectivcly. The clutch member 92 may be shifted by any suitable ineens, but is herein Provided with a circumferential groove 93, 99 having truning lever 101, secured tov e. roclrshaft 102 journaled in suitable bearings in the casing 60. Secured to the rockshaft 102 is a lever 103, connected by a link 104 to a lever 195, which. latter is secured to a sleeve 193 cnc,- clin the shaft 91.

'.llesheft 91 is mounted to rock in suitable bearings 107 and 10S, while the sleeve 106 is mounted Vto rock in a bearing 199, the lutter bearing being formed in bearing bracket Lldmounted on' the side membcrl of the 4frame adjacent the driversseat (seeFigs 7 and 8) Keyed to the shaft 91 is a lever 111, and keyed to the sleeve 106 is a similarlever 112, between which levers is linterposed a manually operable lever 113 pivoted at 11,4K on a bloeit 115 swiveled on the shaft 91. This manually operable lever is en aged olropposite sides as shown in Fig. 8 yfV two springs 116 and 117 secured to the levers 111 andl 112 respec tively. The levers 111 sind 112 are provided with opposed notches 118 and 119, rospeo tively, either of which notches is adapted to receive the lever 113 when the letter 4is the other abotrt the pvot 114. It will mw be evident that by rocking the lever 113 toward the right (Fig. 8), seidlever will be coupled to the lever 112, and the manually operable lever 113 may bethus utilized to shiftthe clutch mem` ber 93, by simply rocking the lever 113 forformed vin the ward or4 backward, as may be required.

Now if, on'the other hand, 1t

be desired to utilize themanually operable lever 113, to

shift the clutch member 73, the manuali operable lover is first swung toward the le t (l `ig. 8), into the notch 118 and thus, being couplml to the lover 111, may then be swung on the axis of the shutt 91, and will thus act through the dcscrilml connections to engage or disongago the clutch 71 at will.

.ne n ineens for providing a selective eontrol of the clutches 71 und 92, I may provide u. plate '120, commonly known as a gate, provided with two longitudinalslots 121 and 122, connected hy n transverse slot v123. The hand lever 113 normally stands i'n the middle oi the slot '123 out of engagement with the forked levers 111 and 112. To disengage the clutch 71, the hand lever 113 is first n'icfvcd laterally from the slot 123 into the slot 121|, and is then moved forwardly (toward the right, Fig. 9) to the end of the slot 121. lf, on the other hund, the operator wishes to engage the clutch 92, he moves the hand lever 113 laterally from the slt 123 int-o the slot 122` With the Yhand-lever in the-slot 122, a forward movement of the lever to the front end of the slot will result in shifting the clutch 92 to cause forward movement of the body, while movement of the lever to the rear end of the slot 92 will cause a reverse movement of the body. r[he hand lever may lbe held in various positions'` of adjustment by spring-pressed pins 124 and 125, carriedby the forked levers 111 and 112, und engaging suitable depressions side of the plate 120.

It will now be evident that the operator, by first placing the gears 32 and 33 in their neutral. position (see Fig. 4), by the use of the usual transmission gear shifting lever {not shown), und then shifting the hand .lever-113 in the described manner, may utilize the power of the engine to cause thel eedecrew to be rotated in either direction, or to be stopped at will.

l will now describe the devices by whichy the rearward n'rovemcnt of the body, under the influence of the described connection, is utilized to enforce a tilting, or'dum'ping ,l n o v ement. if, after the bodyr has been moved rearwardly until the wheels 99 enter 4the wheelreeeiving depressions 19-19, some means isprovider'l for preventing further rearward movement of the bod continued movcn'icnt of the feed-nut und t e body link will result in a tilting or dumping action, (see Fig. 2). Asa means for limiting such rearward movement ofl the bodyV to enforce a tilting action, there ay be g ovijded a pair ofstops 126-426, 4ounte on pivots 127 -127 on the arms 1 6-16 which form the rearward extensions of t erails These stops are herein in theA foi'm ,of hooks# lt will be readily apparent that which may be held raised in the position shown in Figs. 1 and 5 128, secured to a rock-shaft 129 mounted to rock in suitable bearings provided in the arms 1G. Stops 130 serve' to limit the swinging moven'ient'. oi the latches or dogs 128 toward the right (Fig. 5),. while stops 131 sei-re to limit swinging movement of said dogstonard the left. The stops 126 are adapted to, receive trunnions 132 carried by the body 7 concentric with the wheels 9. and held in the brackets 13. ln fact, these trunnions may constitute shafts for the wheel 9, and may have formed on their outer ends ...the pins 24 hereinbcforc referred to. vWhen the 'body 'is moved rear\vardl v and the wheelsy 9 roll down the incline 1T into the depressions 19, the trunijiions 132 engage am sur-faces 133 formed on the stops 126,

f and lift the latter to a sullicicnt extent to allow the trnnnions to 'pass into trunnionreceivingslots .134, whereupon the stops will drop. and will thus interlock with `the trunnionsl and securely hold the latter, so that continued. uioveincnt of the toed-nut and vtail-board `will lift about its pivots, and no undue strain will be brought upon these pai-ts. The board may. be normally locked iu its closed position by a pair of latches 138--1 38, in the formof well-known engaging pins 1395-139 on the tail-board, these latches being secured to a rock-shaft 140, mounted in bearings upon the body. .-The latch 138, upon' one side of the body (see -l `ig. 1) isv provided with 'an arm 141, through which' passes a rod 1,42, having secured thereto a collar-143, serving as an abutment for thearm 141, against which abutment said arm vis normally heldl by a coiled spring 145i, ybearing at its opposite end against a collar 145, secured to said rod. The rod 142 may hi- ,aiftua-teil. by' any suitable means to cause the same to release the tailboard at the moment of dumping, but herein the forxiv-.1rd enrh'of the rod. is pivoted to an arm' 146,.;sccu1'cd vto a. rock-shaft 147 journaled in a bearing bracket 148, and having secured tlreretoa tripping arm 149 adapted to -engage the. cam surface 13301 one of the stops 126 (Fig. 2).l When this occurs, 'whichv will `be just before, the position shown in Fig. 2

is rejched, ytige., tail-hoarcil will be released by latches, or dogs,

160 on the side ot the angle irons 4'?.

will snap down upon the'pins 139, `thereby andallowed toifsywing open, and meent-nowing material i rom the body will naturally swing the'tail-board rearwardly and out o the way of the discharging material.

When thefull dumping position has been reached, the operator may stop the rotation of the feed-screw and reverse the same by the use of the hand'lever 113, but if desired, this action may take place automatically, tlnrough'mechanism which I will now describe. lonnecting the arms 16 is a rod 150, upon which a sleeve 151 is mounted for rocking movement. Tothis sleeveis secured a. bell-crank lever 152, carrying a-body-engagving member 153` which may be adjustably mounted therein, todetermine the point at which the disengagement of theclutch 92 will take place. The bell-crank lever 152 is connected byv u link 154- to a lever 155,'pivoted'at 15G on one of the angle irons 17 (see Figs. 3 and 5). A second link 157 also pivoted to the lever 155 extends forward und is pivoted to a lever 158 secured to a. rock-shaft 159 mounted in .suitable beariigs e. cured to the rock-shaft 159 is a lever 161 connected by a link 162 to the lever 103 hereinbefore referred to. It will be, reinembored that the lever 103 operates to shift the reversing clutch 92. It will now be evident that when the body reaches a certain predetermined oint in its tilting movement, its bottom will engage the member 153, and will act through the connections just described to shift the member 93, and stop the movement ofthe feed-screw. The body-may now-be caused to return to itsnormol position, under the power of the engine, by

'utilizing the hand-lever 113 tol shift'the clutch member 93 into engagement with the clutch member 97, whereupon the feed- I screw will rotate in the reverse direction.

VWhen thebody starts to return toward its' g normal position, the closing of the tail-r board is insured by the pivot' 1,37 being located forward of the plane of the tail-board, and the center of gravity of, the tail-'board' I being consequently located in the plane at the rear of said pivot. Toward the .end of the closing movement of theitail-board, 'the 115 pins 139 will engage the inolinede'freai;` ends 'of the latches 138, 'and lift thelattertfainst the tension of the springs 144, whic' are provided for this purpose, and the latches securely holding the tail-board closed.

If desired, the hook-.shaped stops 126inay be provided with springpressed 16S-e163, to prevent 'saidistops from 115cv-' 4 ing the dogs or latches 128, when the truck'xig istraveling ove'i` rough roads. `When the stops 126are-'in their raisedp a., sition, 'the spring-pressed ,pins`163f may "en-1 gage bosses 164 provided` with depressions yare in-their lowered position, the spring' pressed pins may enter depressions 166 provided in the bosses or stops 131, hereinbefore referred to.

In order that a truck may be kept in use as continuously as possible with the minimum amount of time for loading and 'imloading, it is desirable to provide more than one body for a given truck, so that when the truck is hauling a load.inone body from one point to another, another body may be loaded with materials, and the second body substituted for the first body in a few moments, when the truck has returned with the previously unloaded body.' In order that this maybe accomplished quickl and conveniently, I have provided a bo y which is not only adapted to dump its load under the power of the engine, but which is also so constructed that the body may be entirely removed from the truck, and replaced there- Von underthe power of the engine.

Referring now to Figs. 12, 13 and* 14, the operation of removing and-` replacing Athe body will be described. When it is desired to remove the body, the truck is backed up to:4 an unloading platform of suitable height, exemplified by the platform 167. The dogs 128 are then rocked into the position illustrated in' Figsl and 14, and the stops 126 are lowered into the positions shown in Said figures, so as to be entirely out of the path of the trunnious 132. The operator then brings the power oftheengine into'ilay, to U in` the manner hereinbefore( describe causethe body to be moved, under the power of the engine, rearwardly along the truck frame, and the body will bedelivercdupon theiunloading platform 167 in the manner illustrated in Fig. 13, iirst the pair ofwheels 8 resting'upon the platform, and then' the reiniiining wheels` in 'succession ,passing through `the truckframe onto the platform in an obvious manner. iVhen this has taken place, the hook Lit? of the body link 48 Will be automatically disengaged from the trun nion 423 (see Fig. 12) by engaging a pair of inclined surfaces 168 which will lift' the y hook and free it from the trunnionsn an obvious manner, the openingr in the hook l being-.somewhat 'elongatedfor the purpose 1503;,gthus causing the reversing'clutch to be of facilitating the disengagement. Atthis,

moment, one of 'the rollers 44 carriedby the feed-nut 39 engages the lever 155, and acts through the links 157, lever 158, rock-shaft 1,59, lever 161, and link 162, to rock the lever disengaged, whereupon the movement of the feed-screw and nut will cease.

Now, assuming that it is desiredto replace the body, or place another body upon the truck, the selected body is first brought into position upon the loading and unloading platform substantially in line with the truck, and the-hook 49 of the body llink 48 r the feed-screw slightly.

matically in Fig. let, and will then ride nlp s onto vthe inclined surface 17. The Whee 10, 9 and 8, will then follow alon in order, it being evident that as the loaded` varices alongthe truck frame, the latter will gradually sihk 'upon its s rings and will approach thev level of the oadin and unloading platform. When the body reaches4 its normal position upon the truck framew/ one of the rollers 14 carried by the feed-nut 39 will engage a lever 169,eonnected by a link 170 to the lever 158, and will ac t through these connections, and through the connectionsl hereinbefore described, to disengage the reversing clutch, and thus cause thel rotation of the feed-screw to cease, whereupon the body will stop.` lt will be understood, however, that it desired, the automatic operation may be dispensed with, and the stopping and starting of the' feed-screw may be accomplished by the use of thev hand lever, in the manncr'hereinbefore described. While I have herein shown and described one specific embodiment of my invention for illustrative purposes, and have disclosed and discussed in detailthe construction and ar-4 rangement incidental to one specific applibody ad- 1.
